@make_label_bpm()
@make_label_bpm(start:numeric)
@make_label_bpm(start:numeric, stop:numeric)

returns a map associating the event labels to the BPM at this point in the score. Events with no label or with a zero duration (grace note) do not appear in the map.

Called with no arguments, the events considered are all the events in the score. With start, only the events whose position (in beats) is greater than start are considered. If a stop is also specified, all events must have a position between start and stop.

For example, with this score:

       NOTE D6 1    event1
       NOTE C7 0    event2
       BPM 120
       NOTE D6 2  event3
       NOTE C7 2
       CHORD (D1 A7 Eb7) 4 event5
       BPM 30
       trill (CC6 D7 A7) 2 event6

the call @make_label_bpm() returns

    MAP{ ("event1", 1.0), ("event3", 0.5), ("event5", 0.5), ("event6", 2.0) }

BEWARE: Contrary to the functions @make_bpm_tab and @make_bpm_tab and despite the function name, the value associated to the key in the returned map is not in BPM but is second per beat, i.e. $\frac{60}{\text{bpm}}$. This is expected to change.
